“…Secondly, the ARB process is the only promising SPD technique in industrial scale up for continuous manufacturing bulk ultrafine‐grained (UFG) metallic sheets or plates. Nowadays, the ARB technique has been successfully performed on aluminum, interstitial free (IF) steel, copper, titanium, partial magnesium alloy, and metal matrix composites . However, there are few literatures about using ARB technique to prepare Mg–Li alloys with refined grains and improved mechanical properties.…”

Accumulative roll bonding (ARB) technique is used to manufacture fine-grained and high-strength Mg-8Li-3Al-1Zn alloy. Then, investigate the microstructure and mechanical properties. Results show that, the ARB-processed sheet possesses good bonding performance. The ARB refines the grains and causes the phase distribution to be scattered. With the increase of ARB passes, the s 0.2, s b , and hardness values are enhanced, whereas the elongation value first decreases, then slightly increases with the increase of ARB passes. The ARB5 sheet possesses the smallest grain size (about 3 mm) and the best comprehensive mechanical properties, the tensile strength, elongation, and hardness are 287.02 MPa, 12.5%, and 77.2 HV 0.05 , respectively.

“…properties is attributed to the initial rolling texture of the magnesium sheet which favors deformation along the RD. Such anisotropy in the stress-strain curves was also similarly reported in the ARB process of AZ31 alloy [91,125]. To understand the above observation, X-ray diffraction analyses were performed on the annealed samples.…”

“…However, only cDRX was reported in equal-channel angular pressing (ECAP) process [69]. Several reports also indicate the role of rDRX and cDRX during SPD in processes such as accumulative roll bonding (ARB) [125], extrusion ECAP (EX-ECAP) [124] and cyclic extrusion compression (CEC) processes [122]. There are many factors that influence the recrystallization mechanisms such as the temperatures, strain rate, alloy composition and processing conditions.…”

“…Texture analysis is a very critical means to explore the grain oriental of metals during plastic deformation so that we can more clearly understand the changes in the microstructure of the material. Existing researches have focused on the texture evolution of single metals or alloys [24][25][26][27][28][29][30][31] prepared by the ARB technology. However, the investigation on the texture of multimetal composites is insufficient.…”

The Al-Nb/Ti/Ni composite was fabricated from pure Al, Ni, Ti, and Nb sheets by the ARB technology. The microstructure evolution was observed by scanning electron microscopy, x-ray diffraction, and transmission electron microscopy. The evolution was evaluated by the electron backscattered diffraction (EBSD) technique. A couple of results we obtained showed that the microstructure of Al changed from equiaxed grains to a lamellar structure, and the grain size in the ND decreased gradually. Finally, the average grain size in the ND was 0.31 μm. Additionally, the fraction of HAGBs increased after the third pass, resulting from the dynamic recovery and the shear bands. The texture evolution was tested by electron backscattered diffraction. After the fourth pass, the Al exhibited a combination texture of rolling texture and shear texture. The rolling texture components were composed of Copper{112}<111>, Dillamore{4 4 11}<11 11 8>, S{123}<634>, and Brass{011}<211>, and the shear texture components were Rotated Cube {001}<110> and {111}//ND. The microhardness of Ni, Ti, Nb, and Al was improved in the ARB process and finally reached 226.4, 246.3, 187.2, and 44.2 HV, respectively.
